2 Claims. (Cl. 141--18) ABSTRACT OF THE DISCLGSURE A rechargeabledispenser having a closed cylindrical dispensing container with an inletat one end and a nozzle outlet at the other end, the inlet adapted toreceive a connection from a Water hose, a ball valve mounted incommunication with the inlet and having spring bias means to allow waterfrom the hose to enter the cylindrical container when the container isunder suflicient pressure to overcome the spring bias, a release rodextending from the valve and being connected through the nozzle end ofthe cylindrical container to cause the ball valve to open preliminary toapplying Water to the inlet, and a ball check release valve in thenozzle to release the liquid contents of the cylindrical container uponexcess build-up of pressure therein, and a stop cock having mountedtherein the ball check release valve and operable when the stop cock isin a CLOSED position.

The present invention relates to an improved rechargeable dispenserapparatus, and more particularly relates to an improved rechargeabledispenser apparatus in which certain safety and pressure-release meansare provided so that the apparatus is prevented from any explosion ordeterioration of the equipment upon subjecting the apparatus to anyexcessive pressure effects that otherwise would cause the apparatus toexceed capabilities for which the rechargeable dispenser apparatus wouldotherwise be designed for being used.

An object, therefore, of the present invention is to provide safety andpressure release means for controlling the pressure upon liquids beingapplied to the rechargeable dispenser apparatus, and also continue theeffects of the safety capabilities even while ,the apparatus has beenchecked out, since often the amount of pressure within a container maybe caused to build up upon change of temperature or other residualcircumstances.

In accordance with the present invention, the rechargeable dispenserapparatus of the present invention is adapted to mix and dispense asolution with water and solution mixed together.

A further object and feature of the present invention is that animproved structural combination of elements is disposed and provided fordispensing in which the container of the invention may be filled orcharged with a liquid or main fluid to be dispensed and is poured intothe container upon manually withdrawing or opening a ball check valve,and then water or other mixing liquid may be introduced into thecontainer for mixing therein while the pressure of the applied liquidovercomes the force or bias of the ball check valve until the containeris filled and the pressure within the container equals that of the waterpressure being applied to the inlet. Thereafter, when any excessivepressure is caused to be generated by foaming or other action within thecontainer, a secondary ball check release valve in the nozzle structureor in a stop cock mechanism disposed within said nozzle line may 'beused to release excessive and dangerous values of pressure which wouldotherwise cause damage or explosion to the rechargeable dispensercontainer.

The above and other objects and advantages of the invention will becomeapparent upon full consideration of the following detailed descriptionand accompanying drawings in which:

FIGURE 1 is a cross-sectional view of the rechargeable dispensercontainer showing the essential and preferred component structures;

FIGURE 2 is a cross-sectional view taken along lines 2--2 of FIGURE 1;

FIGURE 3 is a cross-sectional view taken along lines 3-3 or" FIGURE 1;

FIGURE 4 is a cross-sectional view taken along lines 4-4 of FIGURE 3;and

FIGURE 5 is a cross-sectional view showing the component parts of thesecondary ball check release valve as shown and taken along lines 55 ofFIGURE 4.

Referring now to the drawings, there is shown a closed cylindricaldispensing container 10 having a faucet or hose-receiving recess 12 atone end thereof in which there is an inlet 14 adapted to receive aconnection from a faucet or water hose shown schematically at 16. Theinlet 14 includes a rubber or resilient formed seat 18 which is adaptedto secure a firm and fast, non-leak connection for a faucet or hose 16which may be applied and held thereto. The upper contour 20 of thefaucet receiving recess 12 is adapted to come into contact with theperipheral portion of the faucet, as shown, so that when a faucet isapplied and inserted into the recess 12, it may beheld firmly by thecontour 20 of that portion of the recess 12 so that there is no leakageas the faucet is applied to the rubber or resilient seat 18 of the inlet14. The inlet 14 is coupled to n communicating orifice or conduit 26that terminates in a ball valve and seat '28, 30. The ball 30 isconnected by a release rod 32 to a handle 34 which is pulled to releasethe ball 36 from the ball valve seat 28 and a spring biasing meansincluding a spring 40, a spring resting means 42, and a rod limitstructure 44, are provided to encompass the operation of the springbiasing means. The support 42 is mounted on the end of a hollow shaft 46which in itself is mounted from an end of the cylindrical container, asshown. In order to main tain non-leakage characteristics, there is apair of seals 50, 52 provided for eliminating leakage of the internalfluids or liquids of the container from leaking out along the shaft 32.In FIGURE 2, there is shown the seal 52 along with the shaft rod 32 andthe enveloping portion 46a.

In dispensing the mixed fluids that may be applied to the container, itis first noted that the handle 34 is extended for overcoming the springbias means provided by spring 40 so that the ball 39 is displaced fromthe valve seat 28, and a liquid or other material sought to be mixedwith Water or the like, is applied to the inlet 14. After the initialmaterial is applied through the inlet 14, the handle 34 is released andthe ball 30 closes upon the ball valve seat 28. Then a faucet or hose 16is applied into the recess 1.2 and, in the case of a faucet, the upperportion of the faucet rests against a contour 20 so that there is asmall force applied in holding the faucet against the resilient seat 18,and water is thence applied through the faucet and overcomes thepressure of the spring bias means provided by the spring 40 so that theball 3! is accordingly displaced downwardly. When the container 10 isfull, the pressure within the container equalizes with the pressure ofthe water in the faucet or hose 16 so that the force of the springbiasing means in the spring 40 is caused to close the ball against theball valve seat 28, and then no more liquid is able to enter into thecontainer It).

In the event excessive pressures develop within the container 10, thereis a discharge pipe 60 that extends across the length of the containerltl, as shown, and terminates in a nozzle 62 as shown in FIGURES 1, 3and 4. The nozzle contains a stop cock 64 that is adapted to turn atleast substantially 90 as provided within terms of a limit means 66. Thestop cock shown in FIGURES 3 and 4 is in the OPEN position, but the stopcock may be disposed in a CLOSED position upon rotation thereof in acounterclockwise direction, as may be imagined. When the stop cock isthus rotated in the counterclockwise direction with respect to FIGURE 4,then the nozzle and the nozzle pipe 60, 62 are in alignment with asecondary ball check release valve '70 so that, as shown in FIGURE 5,upon excessive pressure being applied from the container 10 through thenozzle pipe 60 and through the communication inlet 72 of the ball checkrelease valve 7t), then the ball 74 of the valve is displaced in adirection that would be downwardly as oriented with respect to FIGURE 5,so that the inlet 72 is opened and excessive pressures are released bythe fluid passing through the inlet 72 and exhausting from the chamber78 through an orifice 80 that would communicate with the nozzle orifice'82 in the nozzle 62.

Thus it is seen that the arrangement of the invention provides a seriesof safety components and valves which release and prevent excessivepressures and eliminate explosions or over-pressuring of the dispensercontainer.
